A fluorinated OPA monomer containing the base thymine ((Z)-t-F-OPA) was synthesized in 12 steps, featuring a highly selective allylic over
homoallylic Mitsunobu substitution for the introduction of the nucleobase. F-OPA modified PNA decamers were prepared by the MMTr/acyl
protection strategy. The thermal stability of duplexes of PNA decamers containing (Z)-t-F-OPA units with antiparallel complementary DNA was
measured. We found a strong dependence of stability from the sequential position of the (Z)-t-F-OPA units, ranging from ¢Tm of +2.4 to -8.1
°C/modification relative to unmodified PNA.
